👉 I'll go with "Air Spray." It's a term that comes from the popular movie "The Lord of the Rings," where hobbits use this term to describe something being sprayed out of a barrel or container, usually in a hostile manner.
Example sentence: In the final battle scene of The Lord of the Rings, as Frodo and Sam were fighting Mordor's army with their own hands, they saw a massive, thick mist coming from an air spray. "I can't believe he used that to destroy this whole place!" exclaimed Aragorn.
